Price Ceiling

Price ceiling: no more than a dollar a square foot in rent. And yes, it’s called rent control.

Price floor: you can’t sell arsenic for less than $100/gallon, because, well, probably too many people would die if they drank it.

So yeah…when the government sets a maximum price for something, that’s called a price ceiling. The rent control measures in New York City establish a price ceiling for the rental rates of certain buildings, built in certain times, with certain tenants. The process is rife with corruption (many wealthy people live in these rent-controlled buildings), but for our purposes, just know that they set a max rental rate, and that’s a price ceiling.

The intention behind setting a price ceiling is arguably a good one: a certain good or service has become so expensive that it’s nearly impossible for many people to afford, so we want to make it more affordable. How many times have we said to ourselves, "I wish this thing that I need was cheaper?" Price ceilings are the government’s way of trying to make that wish come true. But, like all things literary, there’s a price to pay for trying to defy gravity.

Of course, setting a price cap can deliver unintended consequences. If a price ceiling is set below the equilibrium price for that good or service, a shortage results. What’s an equilibrium point? In economic terms, it’s where supply and demand meet. It shows how supply changes as prices change: that’s the supply curve. If there’s a lot of demand for a given product at a given price, if it makes sense to produce more, than producers will…produce more. Duh. Then there's the demand curve, which shows how demand changes as prices change. Where the two curves intersect is the equilibrium point. It’s where the market reaches a balance between supply and demand. That is, it’s where the prices are such that sellers and buyers are both equally happy and unhappy. Kind of like Mom at Thanksgiving.

But what happens if the government mandates the setting of an artificial price? That is, they don’t let the market reach its equilibrium point? Yeah...you get problems. In the case of rent control, you’ve got a price below the equilibrium point. You end up with too much demand for too little supply. Like...who wouldn’t want to pay $400 a month for a beautiful 4-bedroom apartment overlooking Central Park?

Another example. Immediately after a snowstorm, people run to the store to get road salt (if you live in California or anywhere else where changes in weather don’t exist, people put salt on roads so the ice on the roads melts off because, uh… science). In order to make driving and walking conditions safe, the government caps the price of rock salt so that everyone can afford it. And this makes sense, because it would be bad for a whole lot of innocent street-walkers, er, rather, people walking on the street, to have a bunch of road unsalted and icy, and drivers then running into them. In essence, in forcing rock salt prices to be low, the government is protecting a bunch of innocent potential victims. But there is a price to pay in this protection. The low prices mean people bum rush stores and clear ‘em out. The shortage of rock salt comes about because stores can’t meet consumers’ demand.

Let’s say we live in a city where the equilibrium price for a one-bedroom apartment is $1,200, and the government institutes a price ceiling of $1,000. The price cap messes with the market, impacting both supply and demand. Demand is increased, because now there are people who can afford the apartment who couldn’t come up with the cash when it was $200 more expensive. That’s the government’s goal: to let people afford these apartments who otherwise...couldn’t.

But the policy also affects supply. A government price control obviously doesn’t instantly destroy a bunch of apartments. But it changes the incentive structure to make it less profitable to rent out these apartments. Owners will start looking for places to put their resources. They may turn the apartments into condos. They might sell the buildings altogether or try to turn it into retail space. Over the long run, fewer new apartments of this type will be built, because investors aren’t there for the current price structure.

The opposite of a price ceiling is a price floor, which is a government-imposed limit on how low the price of a good or service can go.

Example:

After the Great Depression, the U.S. government instituted several price floors in agricultural markets in an effort to protect farmers from the horrible economy. This was all part of the New Deal...that thing Franky D. came up with to give victims of the Depression. A bit of financial relief.

Let’s bring things forward in time a bit. Pretend the government decided to set a price floor of $5 for the newest iPhone. That means no one could charge less than $5 for the new iPhone. Since new iPhones clearly cost the manufacturer (Apple) more than $5—like, a bunch more—we can say with some confidence that the equilibrium price for an iPhone is higher than the price floor. In this situation, the price floor has pretty much no effect on anything.

Right? Because Apple has no incentive to make any more iPhones if they cost them, say, $200, and the government is telling them they must sell them for more than $5 each. Well, of course they will. iDuh.

But let’s say that price floor was changed from $5 to $500, and now no one can sell an iPhone for under five hundred bucks. That changes things a little, doesn’t it? First of all, most of us are probably not going to run right out and buy a new iPhone. Second, anyone who does pay $500 for their phone is now paying a price that is higher than the equilibrium price. Third, given the dramatic drop in demand, Apple’s going to end up with a major surplus of iPhones, if they don’t do anything about supply. Like…they’d better cut back on supplies, because now this ultra-expensive iPhone is going to have less volume demand than it would if it sold for, say, $300.

Assume the equilibrium price for an iPhone is $250. Apple is selling iPhones at an artificially high price; that is, a price above the equilibrium point. There’s a big gap between where the price floor hits the supply curve and where it hits the demand curve. At $500, Apple wants to make a lot of iPhones. But unfortunately for them, not many people want to buy at this price.

There are benefits and drawbacks to price controls. They can protect consumers by making sure they can afford what they need, and they can protect companies by making sure they won’t go broke producing their goods and services that they might not otherwise make. But they can also lead to economic disequilibrium, where supply and demand are artificially controlled and lead to shortages and surpluses.

Like finding an affordable apartment in the Windy City, instituting price controls involves making some trade-offs.

no macro economics Allah shmoop price ceilings and price floors

00:09

Yeah here's a price ceiling No more than a dollar

00:12

a square foot in rent And yes it's called rent

00:15

control And here's a price floor You can't sell arsenic

00:20

for less than 100 bucks a gallon because well probably

00:24

too many people would die if they drank it Yeah

00:26

it's a poison all right so yeah when the government

00:29

said some maximum price for something that's called a price

00:32

ceiling the rent control measures in New York City establish

00:35

a price ceiling for the rental rates of certain buildings

00:38

built in certain times With certain end it's The process

00:42

is rife with corruption like many wealthy people live in

00:47

these rent controlled buildings and take advantage of the system

00:50

But for our purposes just know that they set a

00:53

max rental rate and that's a price ceiling Like you

00:57

know you can rent it for more than whatever per

00:59

foot per month Yeah alright The intention behind setting a

01:03

price ceiling is arguably good One a certain good or

01:06

service has become so expensive that it's nearly impossible for

01:10

many normal people to afford So you know the government

01:15

wants to make it more affordable Well how many times

01:18

have we said to ourselves I wish this thing that

01:21

I need was cheaper fry ceilings or the government's way

01:24

of trying to make that wish come true But like

01:27

all things literary there's a price to pay for trying

01:30

to defy gravity Of course setting a price cap can

01:34

deliver unintended consequences if a price ceiling is set below

01:38

the equilibrium price for that good or service a shortage

01:42

of results Alright so what's an equilibrium point In economic

01:46

terms it's worth supply and demand meet Check out this

01:49

graph again it It shows how supply changes as prices

01:52

change That's the supply curve It's on very Kirby here

01:57

Just supply line If there's a lot of demand for

02:00

given product at a given price well if it makes

02:02

sense to produce more thin producers will produce more Yeah

02:07

duh Like who doesn't want to make money Now check

02:10

out this graph Well It shows how demand changes as

02:14

prices change That's the demand curve where the two curves

02:18

intersect While that's the equilibrium point right where if supply

02:21

equals demand it's where the market reaches a balance between

02:25

supply and demand And that is it's where the prices

02:28

are such that sellers and buyers are both equally happy

02:32

and unhappy with the price they're paying for a given

02:35

number of transactions You know kind of like Mama Thanksgiving

02:39

equally happy and unhappy But what happens if the government

02:44

mandates the setting of an artificial price That is they

02:48

don't let the market reach its equilibrium point You know

02:51

you got problems all right In the case of Rent

02:54

Control you've got a price below the equilibrium point Living

02:57

right down here somewhere you end up with too much

03:00

demand for too little supply Like who wouldn't want to

03:04

pay 400 bucks a month for this beautiful four bedroom

03:07

apartment overlooking Central Park Its market price is probably like

03:05

20 grand a month Another example Immediately after a snowstorm

03:16

people run to the store to get road salt and

03:19

if you live in California or Arizona or anywhere else

03:23

where changes in weather don't exist people put salt on

03:27

roads so the ice on the roads melts off because

03:31

you know science In order to make driving and walking

03:34

conditions safe the government caps the price of rock salt

03:38

so that everyone can afford it And this kind of

03:41

makes sense right Because it would be bad for a

03:43

whole lot of innocent streetwalkers are rather you know people

03:46

walking on the street to have a bunch of road

03:49

unsalted and icy and you know driver's running into them

03:54

You know it's not good in essence forcing rock salt

03:57

prices to be low The government is protecting a bunch

04:00

of innocent potential victims but there's a price to pay

04:03

for this protection The low prices mean people bum rush

04:07

stores and clear amount of supply The shortage of rock

04:11

salt comes about because stores simply can't meet consumers The

04:14

man All right well let's see what this looks like

04:17

on a graph Let's say we live in a city

04:19

where the equilibrium price for a one bedroom apartments 1200

04:22

bucks and the government institutes a price ceiling of a

04:24

grand Well the price cap messes with the market impacting

04:28

both supply and demand Demand has increased because well now

04:31

there are more people who can afford the apartment who

04:34

couldn't come up with the cash when it was $200

04:37

Mohr expensive That's the government school toe Let people afford

04:40

these nicer apartments who weatherize couldn't But the policy also

04:45

effects supply a government Price control obviously doesn't instantly destroy

04:51

a bunch of apartments but it changes the incentive structure

04:54

making it less profitable for the landlords and the shareholders

04:58

of the buildings To rent out those apartments well owners

05:02

will start looking for places to put their resource is

05:04

other places like not in improvements in the buildings They

05:08

may turn the apartments into condos They might sell the

05:12

whole building's altogether or try to turn the whole thing

05:15

into retail space over the long run Fewer new apartments

05:19

of this type will then be built because investors aren't

05:22

incentivized to do so The current price structure makes no

05:26

sense for him so well that's kind of bad Well

05:29

are the opposite of a price Ceiling is a price

05:32

floor which is a government imposed limits on how low

05:35

the price of a good or service can go Example

05:39

Well after the Great Depression the U S Government instituted

05:41

several price floors an agricultural markets in an effort to

05:45

protect farmers from the horrible economy Well this was all

05:48

part of the New Deal you know that thing Frankie

05:50

D came up with to give victims of the Depression

05:53

about a financial relief Okay so let's bring things forward

05:56

In the time of it pretend the government decided to

05:59

set a price for five bucks for the newest iPhone

06:02

That means no one could charge less than $5 for

06:05

the new iPhone Well since new iPhones clearly cost the

06:08

manufacturer and mostly apple more than five bucks well like

06:13

a a bunch more than five bucks we can say

06:15

with confidence that the equilibrium price for an iPhone is

06:18

higher than the price floor Well in this situation the

06:21

price for has pretty much no effect on well anything

06:24

right because Apple has no incentive to make any more

06:26

iPhones if they cost them say $200 each and the

06:30

government is telling them they must sell them for more

06:32

than $5 each So of course they will sell them

06:35

for more than $5 each Ida But let's say that

06:39

price floor was changed from $5 toe $500 Well now

06:45

no one Khun settle an iPhone for under 500 bucks

06:48

Well that changes things a bit doesn't it First of

06:50

all most of us are probably not going to run

06:52

right out and buy a new iPhone for $500 in

06:55

second Anyone who does pay 500 bucks for their phone

06:58

is now paying a price that is higher than the

07:00

equilibrium price Well Third given the dramatic drop in demand

07:04

Apple's going to end up with a major surplus of

07:07

iPhones If they don't do anything about supply like they'd

07:10

better cut back on building more iPhones Because now this

07:14

ultra expensive iPhone is going to have less volume demand

07:17

then would it If it's sold for say 300 bucks

07:20

All right let's look at this on a graph Assuming

07:22

the equilibrium price for an iPhone is a $250 Apple

07:26

is selling iPhones at an artificially high price That is

07:29

above the equilibrium point up here Will you Khun see

07:32

the place where the price floor hits the supply curve

07:35

You can also see where the price for hits the

07:37

demand curve Right here There's a big gap between the

07:41

two Well at 500 bucks Apple wants to make a

07:43

lot of iPhones but unfortunately for them not many people

07:47

want to buy a lot of iPhones at 500 bucks

07:50

in thank you very much All right There are benefits

07:52

and drawbacks to price controls They can protect consumers by

07:55

making sure they can afford what they need And they

07:58

can protect companies by making sure they won't go broke

08:01

producing their goods and services that they might not otherwise

08:04

make But they can also lead to economic disequilibrium where

08:07

supply and demand are artificially controlled and lead to shortages

08:11

and surpluses And over the long run you want to

08:13

kind of let the market do your boss right It's

08:16

kind of like finding an affordable apartment in the Windy

08:18

City Instituting price controls well it involves making some major 00:08:22.249 --> [endTime] trade offs
